i WHEELED PLOW.

Application led January 12, 1923.

To all whom t may concern.'

Be it known that I, CAMERON H. GEMBER- LINc, a citizen of the United States, and

a resident. of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Wheeled Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in wheeled plows and more particularly to disk ploWs,-one object of the invention being to provide a disk plow adaptable for use with a tractor as the draft means, and which shall embody a singlefurrow wheel at the rear end and a single land wheel intermediate of the ends, with simple means for angling said wheels simultaneously and also with means cooperable with therear furrow wheel axle for raising and lowering the plow frame.

A further object is to so construct Va wheeled plow having a single rear furrow wheel and a single intermediate land wheel, that said' wheels may be angled simultaneously and caused to be always disposed to travel in parallel paths, and to be disposed in such parallel relation to each other when the plow frame is raised as well as when the plow disks are in working position.

A further object is to provide simple and efiicient manually controlled means whereby a rear furrow wheel of a plow lmay be angled and whereby the frame may be raised and lowered and adjusted for depth plowing by the application of lifting power to the axle of the rear furrow wheel only.

With these and other objects in view, the invention consists Vin certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings;

Figure 1 is a plan view of a disk wheeled plow showing an embodiment'of my invention;

Figure 2 is aside elevation, and

Figure 3 is a rear view.

The frame of the plow includes an `approximately U-shaped main frame beam 1 having forward and reardiagonal portions 2 and 32,-'-the forward beam member 2 be- Serial No. 612,272.

ingextended to provide abeam or frame member 4: approximately coincident with the line of draft of the plow structure, and the rear diagonal member being extended to provide a short rear beam or frame member 5 Ldisposed parallel with the .line of draft. Coupling' devices indicated at 6' are provided for connecting the forward end of the frame beam with a tractor represented at 7, and by means of which latter the plow structure will be supported in work position, as will be readily understood from an inspection of the drawing rand the following description of' various features of the structure.

The plow frame is supported on two wheels,-one of which is a furrow wheel 8 located at the rear end of the frame and the other. is a land wheel 9 located laterally from an intermediate portion of said frame.

In the embodiment of the invention shown in the drawings, two earth-working disks l0. 10, are shown, eachl provided with a suitable mounting indicated at 11. The mounting for the forward disk is carried by a laterally and rearwardly projecting arm or beam 12 `secured to the forward diagonal member 2 of the main frame beam 1 and the mounting for the rear disk is secured to the rear diagonal member 3 of said main frame beam. While I have shown the plow as being provided with two earth working disks, it will be understood that a single disk or a number greater than two might be employed. y

A bracket 13 projects laterally from an intermediate portion of the main frame beam 1 and may comprise two members 14 and 15 secured respectively to the diagonal members 2 and 3 of said main frame-beam as clearly shown in Figure 1. The bracket 13 carries at its free end portion, a bearing 16 for an inclined land wheel axle 17 and the member l5 of said bracket supports another bearing 18 for said axle. The outer end portion of the land wheel axle 17 is bent as at- 19 so that its spindle portion which enters the hub of the land wheel 9 will form a crank disposed horizontally, thus causing the land wheel to stand in a vertical position as indicated in Figure 3. It will be evident that if the inclined land-wheel axle be turned in its bearings, the land wheelv will-be so angled (by reason of the horizontall` spindlev crank on said axle)l from the@ position shown in Figures l and 3 and caused to assume a position at an angle to the longitudinal axis of the plow structure. Such angling of the land wheel may be eilected by operation of a hand lever 20. rlhis lever is pivotally mounted on a frame ot a toothed segment 2l secured to the forward portion l of the main frame beam and provided with a suitable detent for cooper-k ation with said segment. rlhe inclined" axle is provided at its upper end with an up-turned crank 22 and this crank is connected by a rod 23 with the hand lever 20,- one end of said rod being bent laterally to form a pivot pin 2d for effecting pivotal connection ot said rod with the crank and the other end of said rod being bent laterally to form a pin 25 whereby the rod is pivotally connected with the hand lever.

The member l5 otl the bracket 13 is extended rearwardly and terminates in an arm 26 disposed parallel with the rear end portion of the main frame' beam, a brace 27 being located between said arm and the rear diagonal member of said main frame beam. A lever 28 having the shape ot' a bell-crank to provide two arms 29 and 29, is located at the rear end of the main Atrame beam and one arm (29) of this lever is made with a transverse tubular or sleeve portion 30 disposed between the arm 26 and the rear beam member 5 and pivotally connected with the same by means of a transverse bolt indi-cated at 3l. That portion of the lever 28 which unites its two arms includes a vertical sleeve 32 which provides a bearing or mounting i'or the vertical portion et a swivel axle 33 for the rear furrow wheel S, the spindle portion of said axle which enters the hub of said rear furrow wheel being inclined so that said furrow wheel will be disposed in an inclined position as most clearly shown in Figure 8.

The rear end oi` a rod or pitman Pfl is adjustably connected with the arm 29V o'lf the bell crank 28 and the 'forward end ot this rod or pitman is 'connected with a hand lever 35 pivoted to the frame ol a toothed segmentV 36 secured to the forward portion of the main trame beam, and said lever is provided with a'suitable detent to engage the segment 36. n

It will be seen that byoperating the hand lever 35, motion willbetransmitted through the rod or pitman 3e to the bell crank 28, thus causing the latter to be turned on its pivotal connection with the rear end of the frame and power to be imparted to the rear furrowwheel and its axle to raise (or lower) the frameV (with the land wheel serving` as a fulcrumA on the ground) to raise or lower the plow disks or adjust them tor depth of plowing.

. Y The swivel axle 3.3 is provided with a fixed arm 37 which projects Afrom said axle adjacent to its spindle portion, in an upwardly and inwardly inclined direction.,-the upper end oli said arm terminating in a plane which, it extended horizontally, would intersect the rear axle bearing sleeve between the ends ot the same. A rod or pitman 3S. is pivotally connected at one end with the upper end of the rear axle arm 37, said rod or pitman being provided (in the en'ibodiinent ot the invention shown in the drawing) with a hook 39 which engages an eye l0 at the upper end of said arm 37. lThe rod or pitman 3S may be made in two members adjustably connected together, the torward member ll being made tubular and internally threaded to receive a threaded portion l2 et the other member et said rod or pitman. member el may be biturcated to receive the cranl; 2 on the inclined land-wheel axle and pivotally connected to said crank by the same pivot member 24 which pivotally connected the rod or pitman with said axle crank.

With the .construction and arrangement ot' parts as above described, when the hand lever 2O is operated, .movement will be imparted by the rod or pitman 23 to the inclined land-wheel axle and by therod or pitmanBS--el to the arm S7, on the rear 'turrow wheel. axle, so that both land and furrow wheels will be moved in a manner to angle them simultaneously and to the same extent or to bring them from angled positions to positions parallel with the longitudinall axis of the plow structure and the line et dritta-said land and furrow wheels being maintained in parallel lines ot travel at'all times, although the land wheel is dis-v posed perpendicular to the ground and the rear furrow wheel is inclined to counteract land pressure.

llVii'h my improved construction, the substantially parallel relation ot the inclined furrow wheel and the perpendicular land wheel will be maintained when the lifting lever is operate-d as when the shifting or angling lever 20 is operated.

`When the plow is raised orV lowered by operating the lifting lever the rear furrow axle will turn slightly in its bearing on the bell-cia.nlcl.everV28. This slight turning ot the furrow wheel axle is controlled by the furrow-wheel axle-arm 37 which is held in position by the rod or pitman 538-41, the latter being in turn coupled to the shitting lever rod or pitman 28. rlhe location ofthe coupling at 40 between the rear-wheel axle arm 37 and the rod or pitman 38-41 is important especially -in keeping the two wheels parallel while the lifting lever 35 is being operated. l y f Y Various changes might be made in the detailsof construction of my invention without departing from the spirit of the latter i The forward end ot the pitman or limiting its scope and hence I do not wish to restrict myself to the precise details herein set forth.
